Very cool and authentic place to stay. Bua and Note were wonderful hosts. They definitely put their heart into this place and it shows through in the design, hospitality, and unique experience.
I am a woman who is an architect traveling by myself and stayed in both the 3rd floor and 4th floor rooms for two nights.
Overall:
I have to say that both rooms are beautiful, had wonderful natural light, very clean, well laid out, and I can't pick my favorite. The views from both are great - distant temple, skylines, and beautiful sunrise/sunset sky. The location feels very safe, lots of cool small business cafes/bars popping up near by. You can also easily walk to a BTS skytrain line (12min) or catch a cab fairly easily.
The stairs in the building are steep so I don't recommend this for anyone who has difficulty climbing three+ flights.
The internet works perfectly, the beds/linens/pillows are comfy, the AC and ceiling fans keeps rooms cold, showers have great pressure and hot water, and there is a spacious communal living room space with giant tv and fridge for just the two rooms to share!
On my last night Note helped me to book a reservation at their very popular bar/restaurant on the ground level. It was delicious, you definitely must try it whether staying with them or elsewhere.
Comparing the rooms:
The third floor room had a wonderful sitting space next to a giant window looking out over the street.
Some pros about the 4th floor room is that it is a bit quieter as it is further from the streets. The windows are not double pained in either room which means that Bangkok traffic can be heard. It is very quiet at night though but starts early (7:30am) with motorbikes. This is the only potential downside for light sleepers, but the hosts have provided earplugs in each room if it is needed! I didn't need and slept great.
Another potential pro of the 4th floor is that the restroom has a separating curtain which makes it more private, the 3rd floor bathroom is separated with a glass wall - fine for couples but maybe less ideal if two friends.
I hope to make this place my go-to spot when I return to Bangkok in the future, I really liked it and was happy to support a small business that was so well put together, kind owners, and their passion shining through. Excellent experience.
